Bill and Ted. Wayne and Garth. Bert and Ernie. Willy and Waylon. Poncho and Lefty. Mojo and Jojo. Biscuit and Gravy. Ham and Eggs. Brutus and Caesar. Jules and Vern. Fred and Barney. Sushi and Mochi. Spaghetti and Meatball. Goober and Gomer. Thing 1 and Thing 2.
Coco and Gigi...I had kittens with those names that I had to give up because it turned out my husband was allergic. They looked a lot like these 2 cuties.
Scylla and Charybdis? Or Cronus and Rhea. Gilgamesh and Enkidu, Hero and Leander, Indra and Ahalya. Perhaps Karna and Vrishali? In case you were looking less neurotypical names. Or something goofy. Og and Goji, Buckleburry and Picklescott.
